PUF Panel Thickness Guide: How Many mm Do You Need?
Choosing the wrong PUF panel thickness is a common and costly mistake in prefab construction. Too thin, and you lose cooling or heating efficiency. Too thick, and you pay for insulation you don’t need. This guide from Kaizen PreFab helps you pick the right thickness for your project. Quick answer: PUF panels in India are commonly sold from 40 mm to 150 mm. Sheds and site cabins usually need 40-60 mm, chilled rooms 60-100 mm, and frozen storage 100-150 mm or more. What Does PUF Panel Thickness Mean? A PUF (polyurethane foam) panel is a sandwich of two metal sheets with a rigid foam core. Thickness refers to that insulating core. A thicker core slows heat transfer more, so the space holds its temperature with less energy. Standard sizes are typically 40, 50, 60, 80, 100, 120 and 150 mm.
